Sandcrete block, being one of the most important building materials, has become very expensive nowadays and it’s on high demand in Nigeria. In order to reduce its cost and probably increase the compressive strength, this research was conducted to assess the suitability of granite fines as partial replacement for sand in sandcrete block production. The mix proportion (1:6) was used for batching ...

In the present universal scenario where the dependence on heterogeneous multi-core processors is tremendous, dealing with algorithms focusing on coherence between shared caches is imperative. WARP redesigns the replacement policy in the last level cache. In this policy, the shared (clean) lines and the private exclusive line are given the first two priorities dynamically followed by private mod...

abstract in this study the possibility of utilizing date syrup as a sugar replacer in soft ice-cream was investigated. for this purpose control sample was formulated based on iranian ice- cream standard. data syrup which produced from third grade kabkab dates, replaced sucrose in four levels (25, 50, 75 and 100%). physical properties including overrun, viscosity and freezing point (drawing temp...

This paper studies the following online replacement problem. There is a real function f(t), called the ow rate, deened over a nite time horizon 0; T]. It is known that m f(t) M for some reals 0 m < M. At time 0 an online player starts to pay money at the rate f(0). At each time 0 < t T the player may changeover and continue paying money at the rate f(t). The complication is that each such chang...

Failure of many engineering systems usually results from a gradual and irreversible accumulation of damage, a degradation process. Most degradation processes can be monitored using sensor technology. The resulting degradation signals are usually correlated with the degradation process. A system is considered to have failed once its degradation signal reaches a prespecified failure threshold. Th...

Currently, most computer systems consist of Dynamic RAM (DRAM) as main memory and Hard Disk Drives (HDDs) as storage devices. Due to DRAM’s volatile nature, it suffers from data loss in the event of power failure or system crash. With rapid development of new types of non-volatile memory, it becomes promising that one of these technologies will replace DRAM as main memory in the near future. Co...

The buffer-cache replacement policy of the OS can have a significant impact on the performance of I/Ointensive applications. In this paper, we introduce a simple fingerprinting tool, Dust, which uncovers the replacement policy of the OS. Specifically, we are able to identify how initial access order, recency of access, frequency of access, and long-term history are used to determine which block...

Document caching on is used to improve Web performance. An eÆcient caching policy keeps popular documents in the cache and replaces rarely used ones. The latest web cache replacement policies incorporate the document size, frequency, and age in the decision process. The recently-proposed and very popular Greedy-Dual-Size (GDS) policy is based on document size and has an elegant aging mechanism....

Stochastic approximation (SA), a stochastic analog of iterative techniques for finding the zeroes of a function (e.g., Newton-Raphson), is applied to a problem in resource allocation, the age replacement policy (ARP) problem. A stochastically failing unit is replaced at failure or at time t, whichever comes first, under an age replacement policy. When the form of the failure distribution is unk...
